GERG'E F. FSHR, OF PRVIDENCE, RHODE ISLAND, ASSIGNOR TO THE REVERA RUBBER GOMANY. A CORPORATION' OF RHODE ISLAND @ZE-FNISHNG MACHINE.

o au whom t may concer/L: i

Be it known that I, GEORGE FFISHER, a citizen of the United States, residing at Providence` countv ot Providence, and State ot Rhode Island, have invented certain new and useful improvements in Rim-Finishing lilachines. ot which the following' is a t'ull, clear, and exact description.

This .invention relates to the manufacture ot tires, and particularly to apparatus for facilitating the treatment ot' annular inembers in connection therewith.

in the manufacture ot' solid tires, by way orP example, it is customary to prepare the rims 'for the reception of a hard rubber base by removal ot' rust from the channel and coating the same with cement. rthe rust is removed by sand blasting and subsexpiently blowing oli' the particles of Yforeign matter that may remain. Thus cleaned, the rim is brushed with cement in a room at a suitable temperature to expedite drying. `The blowing and coating operations heretofore have been performed by mounting'the rims on a spider or chuck of some sort. Such devices have been found objectionable because they require too much time and labor.

The present invention aims to provide an apparatus that requires a minimum of labor in the manipulation of the rims incident to their treatment, and that oi" such a simple nature that the services of unskilled open ators may be utilized.

yVith the embodiment of the invention illustrated in the drawings in mind, and without intention to necessarily restrict its scope, the invention may be said to consist of rotating parallel members or shafts by which any number of rims may be sustained upright and treated conveniently while turned thereby.

3' rthese are the objects of my invention` and nther objects will appear from the accolnpanying drawings, in which- Figure 1 is a viewlot the apparatus in perspective, ,and l Fig'. 2 is a typical rim section.

its shown in the dralwings theapparatus cinnprises spaced parallel members or shafts l and 2 which are suitably supported at sp; od intervals in standards 3 and inten mediately steadied by bllocks 4. The shafts 1 and 2 are preiercbly but notnecessarily Specification of Letters latent. Pglmumi ,g nel pp SEL nppication filed .uly 8,

located in a horizontal plane at a convenient elevation above the door. Both ot the shafts are intended to be driven, but for some pure poses friction surfaces -migrht be provided on. a driven shat't and the other allowed to remain stationary or run tree. Any suitable means may be employed to drive the shafts such as the belt pulleys 5, shown at one end thereof.

It is desirable but not essential to maintain the temperature of the air in the vicinity of the shafts at a suitably elevated degree to expedite drying ot the cement. For this purpose coilsor pipes 'Y are located'in the rear ot and parallel with the sha'ts or otherwise arranged, and steam or other suitable heating medium may .be supplied there to to maintain the desired temperature.

ill/'ith the above described apparatus, rims G'tliathave been blasted tree ot rust or other foreign matter are placed upon the shafts and'by their own weight trictionally driven about their axes. So mounted, an operator pass along in front ot any number of these rims and blow them clear of minute particles oit' rust or other matter. Then the rims maybe brushed with cement; ln both these operations, no manipulation ot the rims is necessary beyond placing them upright upon the shafts. It to be observed that the apparatus is capable ot handling any size rim and that regardless of its size the peripheral speed of the channels or grooves thereof remains the same.

While it is preferred to arrange the shafts in a horizontal plane, it is to be distinctly understood that the invention is not limited to such form for the shafts might be located in a plane inclined to the horizontal and the rims held upright and rotated. And the apparatus is notI limited in its usefulness to coatingr rims with cement as it may be employed advantageously adjacent and parallel calendering' machines for winding warm sheets of vulcanized composition on the rims and without bothersome manipulation of the easily Vdistorted stock. The invention is therefore not limited to the uses mentioned or details oi." construction illustrated and de- `scribed efccent indicated in the accompany- 'f ing claims tb which reference is made for an "understanding ot scope .ot the iuventicn.

Having thus described my invention,

I claim and desire to'protect by Letters Patent is l. Apparatus ot' the class described cornprising, spaced parallel driven shafts, bearings suppm'ting saidshafts at the ends and intermediately, said shafts being adapted to supportand turn annular riins between theill bearings. and haring their entire length substantially free and unobstructed upwardly for the reception o1 a pluralityot' the rims. Y Y

2. Apparatus oi the class described 'for independentl)v supporting and rotating a plurality of annular tire rims comprising, parallel driven shafts upwardly free and unobstructed for substantially their entire length and ot' a diameter and spacing between centers such that rims may be supported and rotated iu an upright position thereon and such that unobstructed ready access to the rims is afforded operatives for manual operations thereon.

3. Apparatus of the class described for independently supporting andprotating a plurality of annular tire rims comprising, parallel driven shafts supported adjacent and in proximity to the Hoor and upwardly free and unobstructed for substantially their entire lengths, said shafts being of a` diameter and spacing between centers such that rims .may be supported and rotated in an upright position thereon and suoli that unobstructed access to the rims is alforded operatives for performing manual operations thereon While standing on the floor. f
